“…Simultaneously, some bacteria display pesticide-degrading capabilities. In 2022, Zhao et al isolated a β-cypermethrin-degrading bacterium, named GW-01, from sheep rumen food boluses which showed significant degradation of pyrethroid pesticides ( Zhao et al, 2022 ).…”

The rumen serves as a complex ecosystem, harboring diverse microbial communities that play crucial ecological roles. Because previous studies have predominantly focused on anaerobic microorganisms, limited attention has been given to aerobic microorganisms in the goat rumen. This study aims to explore the diversity of aerobic microorganisms in the rumen and understand their niche and ecological roles. Rumen fluid samples were collected from 6 goats at different time points post-morning feeding. pH, NH3-N, and volatile fatty acid (TVFA) concentrations were measured, while In vitro cultivation of aerobic microorganisms was performed using PDA medium. Internal Transcribed Spacer (ITS) and 16S sequencing unveiled microbial diversity within the rumen fluid samples. Evidence of obligate aerobic microorganisms in the goat rumen suggests their potential contribution to ecological functionalities. Significantly, certain aerobic microorganisms exhibited correlations with TVFA levels, implying their involvement in TVFA metabolism. This study provides evidence of the existence and potential ecological roles of obligate aerobic microorganisms in the goat rumen. The findings underscore the significance of comprehensively deciphering goat rumen microbial communities and their interactions, with aerobes regarded as permanent residents rather than transients. These insights form a solid foundation for advancing our understanding of the intricate interplay between goat and their aerobic microorganisms in the rumen.

Enhancing the performance of traditional pesticide formulations by improving their leaf surface wetting capabilities is a crucial approach for maximizing the pesticide efficiency. This study develops an emulsifiable concentrate (EC) of 4.5% β-cypermethrin containing Brucea javanica oil (BJO). The incorporation of BJO aims to improve the leaf-wetting properties of the EC formulation and enhance its insecticidal effectiveness. The droplet size and emulsion characteristics of β-CYP EC emulsion with varying concentrations of the emulsifier were evaluated, and changes after incorporating BJO were assessed to develop the optimal formulation. A comprehensive comparison was conducted among commercial 4.5% β-cypermethrin EC (β-CYP EC-1), 4.5% βcypermethrin EC with BJO (β-CYP EC-2), and 4.5% βcypermethrin EC without BJO (β-CYP EC-3). This comparison encompassed various factors including storage stability, insecticidal activity, cytotoxicity, and wetting performance on cabbage leaves. The results indicated that the ideal emulsifier concentration was 15% emulsifier 0201B. β-CYP EC-2 demonstrated superior wetting properties on cabbage leaves (the wetting performance of β-CYP EC-2 emulsion on cabbage leaves is 2.60 times that of the β-CYP EC-1 emulsion), heightened insecticidal activity against the third larvae of Plutella xylostella [diamondback moth (DBM)] [the insecticidal activity of the β-CYP EC-2 emulsion against the third larvae of DBM is 1.93 times that of the β-CYP EC-1 emulsion (12 h)], and more obvious inhibitory effects on the proliferation of DBM embryo cells than the other tested formulations. These findings have significant implications for advancing pest control strategies and promoting sustainable and effective agricultural practices.

Cypermethrin (CYP) is a commonly used type Ⅱ pyrethroid against pest control in agriculture and household. Its excessive use has the potential to cause serious secondary environmental pollution. Biodegradation in the environment minimizes contamination however the metabolites, could also harm the environment more than the main product of interest. Therefore, optimum degradation rates and possible effects of bioremediation should be understood to evaluate its applicability. In this study, isolates obtained from soil exposed to CYP from fig farms in Adana were investigated to identify their CYP biodegradation pathway, and the key enzymes responsible for biodegradation, to optimize the biodegradation, and to indicate the inhibitors that affect their ability to mineralize CYP. Enterobacter hormaechei strain ZK101 and Stenotrophomonas maltophilia strain ZK102 both degraded CYP with first-order kinetics through esterification followed by 3-phenoxy benzoic acid (3PBA) deoxygenation. Strains accumulated 3PBA when they have been reinoculated to the soil due to the copper present (40 ppm) in the soil causing the inhibition of 3PBA dioxygenase. The work here is the first study that tested the potential of CYP degradation when isolates were re-inoculated in the soil and showed that CYP degraders in the field will cause an accumulation of a more toxic contaminant than CYP. The results of this study help to understand the effects of bacterial applications for CYP contamination and reveal the negative effects of microbial responses in the field.
